Based on resistive negative feedback structure,a 1~3 GHz non?inductive wideband low noise amplifier is presented in the paper.Combined with theoretical analysis,the circuit is designed in SMIC 0.18 μm RF CMOS process.The simulation results show that the wideband low noise amplifier achieves -15 dB matching around the operating frequency,its conversion gain is over 14 dB with 2.6 dB ripple,and the noise figure is less than 3.6 dB.
